The Restless I would say it was the breakthrough hit for the mainstream, all cuz he got Dr. Dre as the main producer, Eminem, Snoop, Krs One, Nate Dogg, DJ Quik, Erick Sermon, The Liks... all big names on one album and thats why he went platinum and be all over MTV since Eminem.
But I still dig his older stuff cuz theyre classics to me.
40 Dayz 40 Nitez
& Speed of Life
...but MvsM was the worst one he put out and he admitted he didnt like it either cuz of very weak commercial production and it was not even promoted as much as it should. It was wack! Thats why he left Dre, Em, & Snoop so he can work on his own from now then...
